This Women's Neutrino 400 down sleeping bag is a game - changer for female adventurers on mountain missions. With a highly tapered design, it cuts out excess bulk, allowing you to move fast and light. It's shorter in length and has a female - specific shape, filled with 400g of 800FP European goose down that's been stabilised in chevron - shaped baffles. This smart design reduces fabric use compared to traditional horizontal baffles, while the trapezoid boxwall baffle construction lets the down loft fully, eliminating cold spots and maximising warmth.
For alpinists seeking a lightweight, low - bulk bag for cold temperatures, the Neutrino 400 offers excellent packability and warmth for its weight. The narrow mummy fit further reduces bulk and pack size. Constructed with high - performance materials, it's ideal for three - season adventures.
Additional baffles along the zip and around the neck reduce heat loss, and an adjustable drawcord on the hood lets you snug the bag around your face. The women's cut is slightly shorter than the regular bag, with a narrower shoulder and a bit wider hip space for comfort and efficiency.
Now featuring a recycled nylon lining and a recycled, wind - resistant Pertex Quantum outer, it's not only wind - resistant but also eco - friendly. The down has a Nikwax fluorocarbon - free hydrophobic treatment to handle condensation. It comes with a ¾ length zip with anti - snag guards, a zipped internal stash pocket, and a waterproof roll - top compression sack for easy storage. Hand - filled in the UK, our down bags maintain the down's loft and warmth as the down is never pre - compressed.




Using your Women's Neutrino 400 down sleeping bag is a breeze. First, unroll it from the compression sack and let it fluff up for a while to allow the down to loft fully. When you're ready to sleep, just zip it up and adjust the drawcord on the hood to keep your face warm. If you want to store small items like your phone or keys, use the zipped internal stash pocket.
When it comes to maintenance, try to keep the bag dry as much as possible. If it gets wet, let it dry naturally in a well - ventilated area. Avoid direct sunlight as it may damage the down and the outer fabric. If it gets dirty, you can hand - wash it gently with a mild detergent and lukewarm water. After washing, rinse thoroughly and squeeze out the excess water carefully. Then, let it dry completely before storing it.
For storage, use the provided waterproof roll - top compression sack. But don't keep it compressed for too long, as this may reduce the down's loft over time. If you're not going to use the bag for a long time, store it in a large, breathable bag in a cool, dry place.
